I have to pass by a bunch corn fields (animal feed) and hay fields on the way home. Couple of times when they first opened up the fields they had their tractor stuck big time not realizing how soft certain areas were, right up over the diffs. they were hauling manure spreaders and the area was right below their barn so I assume it was full of good ole liquid. Good size tractors as well, New Hollands, not sure of the model number but big enough to run duallies front and back. Getting them out, they pretty much destroyed a good sized portion of their new field. Years later, they leave that area untouched.
Side story, before they got stuck, on their first spread around the perimeter which was right beside the road, they sprayed both lanes of the highway (85 KPH road) with liquid manure aka snot. That was bad enough but it was at the bottom of a blind hill on a slight corner that the bikers love to act out their racing dreams. I was going the other way and managed to slow down two bikers coming toward me before they went off roading, scary stuff.
